WH EELED PLOW.

SPECIFICATION forming part of Letters Patent No. 629,732, dated July 25,1899. Application filed January 14, 1899. Serial No. 702,200. (Nomodel.)

To all whom it may concern:

Be it known that I, LEwIs E. WATERMAN, a citizen of the United States,residing at Moline, in the county of Rock Island and State of Illinois,have invented certain new and useful Improvements in Wheeled Plows, ofwhich the following is a specification.

The object of this invention is to liberate the caster-wheel by. themovement of the evener in the team turning corners.

In the accompanying drawings, Figure 1 is a perspective view of aportion of a wheeled plow embodying my invention. Fig. 2 is' aperspective view of my improvements as seen from the top. Fig. 3 is ahorizontal section through the caster-wheel support and locking-lever.Fig. 4 is a perspective View of the linked connection between thecaster-wheel and evener.

The plow in the main is of an old construction, and consists of the beam1, plow 2, axle 3, furrow-wheel 4:, land-wheel 5, and casterwheel 6. Thecaster-wheel is supported by a bracket 7, secured to the plow-beam. The

bracket has an opening 8, within which, is placed a segment 9, providedwith a notch 10 and secured to the shank 11 of the casterwheel. A latch12 is pivoted to the bracket and is held within the notch of the segmentby the force of the spring 13.

To the forward end of the plow-beam is secured a clevis 14, and to theclevis is pivoted anevener-support15. Theevener16isbolted to thesupport.

To theevener-support is secured a bracket having the arms 17 and 18,their outer ends terminating in hooks 19.

A rod 20 has a connection with the upper end of the latch 12 andextendsin the lengthwise direction of the plow-beamand is guided inloops 21, extending from the plow-beam. The forward end of this rod isformed into an eye 22 and stands in a vertical position. To the arms 17and 18 of the bracket, secured to the evener, are connected links 23 and24: by an eye engaging the hook of the bracket. The outer ends of theselinks have a hook 25. These links are passed through the eye of the rodand connected to the arms 17 and 18, when they appear as shown in thedrawings.

When the plow is in working position, the caster-wl1eel will be lockedin connection with the plow-beam, and in turning to the left the hook ofthe link 24 will engage the eye 22 of the rod 20 and move the latch 12out of engagement with the notch 10 of the segment 9; thereby liberatingthe caster-wheel, and the link 23 will move through the eye 22. Inturning to the right the link 23 will draw on the rod 20 and liberatethe latch and the link. 24 will move through the eye 22, and upon theteam drawing in a straight line both links remain neutral and thecaster-wheel will be locked in position.

I am aware that it is old to liberate the cas ter-wheel by a lateralmovement of the pole, also by a frictional connection between thecaster-wheel support and main frame; but I am not aware that thecaster-wheel of a tongueless wheeled plow has been liberated 7o by theturning action of the team independently of the turning movement of thefurrowwheel.

I claim as my invention- 1. In a tongucless wheeled plow, a main frame,a furrow'-wheel, a caster-wheel and means for liberating thecaster-wheel by the turning movement of the team independent of theturning movement of the f urrow-wheel.

2. In a tongueless wheeled plow, a main frame, a furrow-wheel, acaster-wheel, an evener, and a connection between the wheel and evenerindependent of the furrow-wheel.

3. In a wheeled plow, the combination of a main frame, a caster wheel,an'evener, alatch for the caster-wheel, a connection between the latchand evener consisting of a rod connect ed with the latch and extendingforward, its end turned in eye form, two links passing through the eyeand connected to the evener. o

4. In a wheeled plow, the combination of a main frame, a caster-wheel,an evener, a latch for the caster-wheel, a bracket movable with theevener having two arms, one extending each side of the pivotedconnection between the evener and plow-beam, a rod connected with thelatch having an eye at its free end, two links passing through the eyeand connected with the arms of the bracket, the free end of the links inhook form.
